Product details
Overview
AT28C010E-12JU-T from Microchip Technology is a 1-Mbit (128K × 8) paged parallel EEPROM with 120 ns read access time, 10 ms maximum page write cycle, and industrial temperature range (–40°C to +85°C). It operates from a single 5V ±10% supply, features hardware/software data protection, and supports DATA Polling and Toggle Bit for write completion detection-used in firmware storage and configuration retention for industrial controllers.
For engineers reviewing the AT28C010E-12JU-T datasheet, AT28C010E-12JU-T pinout, AT28C010E-12JU-T application, or AT28C010E-12JU-T equivalent, this device delivers deterministic page-write timing, JEDEC-compliant byte-wide interface, CMOS/TTL compatibility, and 100,000-cycle endurance for embedded systems requiring nonvolatile parameter storage without external timing components.
Technical Context
The AT28C010E-12JU-T implements a paged architecture with a 128-byte internal latch, enabling up to 128-byte writes per internal programming cycle. Its dual-line control (CE/OE/WE) allows flexible bus arbitration and eliminates contention during mixed read/write operations.
It integrates VCC-sense circuitry (write inhibit below 3.8 V), 5 ms power-on delay, noise filtering on WE/CE (<15 ns pulse rejection), and optional software data protection (SDP) via three-byte command sequences. The device also includes 128 bytes of dedicated identification memory accessible at 1FF80H–1FFFFH using A9 = 12 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Capacity | 1 Mbit (131,072 × 8), organized as 128-byte pages for efficient bulk writes |
| Read Access Time | 120 ns max - enables direct replacement of SRAM in legacy 5V systems without wait-state insertion |
| Page Write Cycle Time | 10 ms max - deterministic internal timer eliminates need for external write-strobe management |
| Endurance | 100,000 write/erase cycles - validated for high-frequency configuration updates in field-deployed equipment |
| Data Retention | 10 years at +85°C - ensures long-term reliability in unattended industrial environments |
| Supply Voltage | 5V ±10% - compatible with standard TTL/CMOS logic rails and legacy 5V power domains |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade operation without derating |
| Standby Current | 200 µA (CMOS mode) - minimizes quiescent power in battery-backed or low-power sleep states |
Pinout & Package
AT28C010E-12JU-T is supplied in a 32-lead Plastic Leaded Chip Carrier (PLCC) package with matte Sn terminal finish, JEDEC-compliant pinout, and industrial-grade marking ('12' = 120 ns, 'E' = 100K endurance, 'U' = –40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | 17-bit address bus supporting full 128K-word addressing; A7–A16 define page boundaries for page writes |
| I/O0–I/O7 | Bidirectional Data Bus | 8-bit parallel interface compatible with standard microprocessor data buses; supports true read/write without direction control |
| CE | Chip Enable | Active-low chip select; must be stable before address setup; deassertion for ≥50 ns prevents read corruption |
| OE | Output Enable | Active-low output control; used with CE to place outputs in high-Z state and prevent bus contention |
| WE | Write Enable | Active-low write strobe; falling edge latches data; rising edge initiates internal write timer; noise-filtered against <15 ns glitches |
| VCC | Power Supply | +5V ±10% supply; internal VCC-sense disables writes if voltage drops below ~3.8 V |
| GND | Ground Reference | Signal and power return; decoupling required within 10 mm of VCC pin per JEDEC layout guidelines |
| NC | No Connect | Pins 30 (PLCC) and 6/9 (TSOP) are unconnected; must remain floating or tied to GND per board design rules |
| DC | Don't Connect | Pin 1 (PLCC) is internally unused; must not be connected to any net |
Key Features
| Feature | Design Value |
|---|---|
| 128-byte Page Write | Reduces firmware update time by up to 128× vs. byte-write; internal latch frees address/data bus during programming |
| DATA Polling (I/O7) | Enables real-time write status monitoring without polling overhead or external timers - complemented data indicates active write |
| Toggle Bit (I/O6) | Provides asynchronous write-complete detection via bit toggling; usable with any fixed address during write cycle |
| Hardware Write Protection | VCC-sense, 5 ms power-on delay, and noise filtering eliminate spurious writes during brown-out or EMI events |
| Software Data Protection (SDP) | User-enabled 3-byte command lock prevents accidental writes; remains active across power cycles until explicitly disabled |
| Device Identification Memory | 128 bytes at 1FF80H–1FFFFH accessible with A9 = 12 V ±0.5 V - supports unique unit serialization and calibration storage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT28C010-12JU-T | 10,000-cycle endurance; same speed, package, and pinout | Limited to lower-write-frequency applications (e.g., factory-set defaults only) | Select when cost sensitivity outweighs endurance requirements and SDP is not needed |
| AT28C010E-15JU-T | 150 ns read access; identical endurance, protection, and page architecture | Suitable for systems with relaxed timing budgets but same industrial temp and reliability needs | Choose when 120 ns is unnecessary and higher-volume procurement enables better pricing on 15 ns variant |
Compared with AT28C010E-12JU-T, the AT28C010-12JU-T trades endurance for lower cost in static configuration roles, while the AT28C010E-15JU-T relaxes timing constraints without compromising reliability or protection - both retain identical pinout, software protection, and industrial qualification.

FAQ
What is the guaranteed write endurance of the AT28C010E-12JU-T?
The AT28C010E-12JU-T is rated for 100,000 write/erase cycles - verified per Microchip's DS20006331A specification under industrial temperature conditions. This endurance applies to both byte and page write operations and is independent of software data protection status. The AT28C010E-12JU-T maintains full functionality throughout its rated cycle count without parameter degradation.
Does the AT28C010E-12JU-T require external high-voltage programming circuitry?
No, the AT28C010E-12JU-T operates from a single 5V ±10% supply and requires no external high-voltage circuitry for normal byte or page writes. Only the optional chip erase mode and device identification memory access require 12 V ±0.5 V applied to A9 - all other operations, including software data protection enable/disable, use standard 5V logic levels.
How does DATA Polling work on the AT28C010E-12JU-T?
During a write cycle, reading the last written byte returns the complement of that data on I/O7 - once the write completes, true data appears. This allows the host system to poll I/O7 synchronously without timers or interrupts. The AT28C010E-12JU-T supports continuous polling from any time after write initiation, and the feature works identically for both byte and page writes.
Can the AT28C010E-12JU-T be used as a direct replacement for older AT28C010 variants?
Yes - the AT28C010E-12JU-T shares identical pinout, timing, and electrical specifications with earlier AT28C010 versions except for its extended 100,000-cycle endurance and 'E'-marked marking. It is fully backward-compatible in hardware and firmware, requiring no PCB or software changes when upgrading from standard 10K-endurance variants.
What package type does the AT28C010E-12JU-T use, and is it RoHS compliant?
The AT28C010E-12JU-T uses a 32-lead PLCC (Plastic Leaded Chip Carrier) package with matte tin (Sn) terminal finish. Per Microchip's documentation, it is Green (Pb/Halide-free) and fully RoHS compliant - no lead, brominated flame retardants, or other restricted substances are present in the package or die construction.
